Abstract

This invention relates to MRI-based methods and systems useful for diagnosing and clinically assessing the presence, location, and size of cardiovascular disease-associated stationary targets, e.g., thrombi and atherosclerotic lesions, within the vascular system. Methods and systems of the invention allow for improved anatomical information to be obtained from MRI images and allow the clinician to develop more effective treatment plans. In one aspect, the invention provides a method of determining the presence or absence of a stationary target within the vascular system of a mammal wherein two MRI data sets representing images of the vascular system and the stationary target are acquired after administration of a targeted MRI contrast agent. In another embodiment, both a targeted MRI contrast agent and a vascular MRI contrast agent are administered to a mammal, and both a vascular MRI and a targeted MRI data set are acquired.

TECHNICAL FIELD This case relates to magnetic resonance imaging of conditions of the vascular system and cardiovascular disease system, and specifically relates to fixed targets, such as thrombus or atherosclerotic injury in the vascular system, with improved detection, location and clinical evaluation. SYSTEMS AND METHODS Background: Cardiovascular diseases (CVDs), such as hypertension, heart attacks, strokes, angina pectoris' atherosclerosis, and arteriosclerosis, invade millions and are the leading cause of death in the world today. CVDs are mainly composed of narrowing arteries, and they promote organs or tissues, such as the heart. The narrowing is caused by excessive accumulation of fatty plaque along the arterial wall. The composition of the plaque causes an aneurysm and a thrombus, that is, a blood clot 'followed by a thrombus causes thrombosis, a heart attack, and a stroke. The key to CVD treatment is early detection and diagnosis so that appropriate treatment can begin. The correct identification of the presence of CVD in the vascular system, such as the presence of thrombus or atherosclerotic injury, is necessary for the development of the correct treatment process, and the location of the operation or treatment is of great diagnostic significance. The effective detection and diagnosis of plaque formation, aneurysms, thrombi, and other injury or disease processes often requires the use of imaging techniques to visualize the patient's vascular system. This development technology includes X-ray angiography, computer tomography (CT) -5- This paper size applies to China National Standard (CNS) A4 (210 X 297 mm)

Description of the invention (2) and spiral CT angiography, and magnetic resonance imaging (MRI). The use of magnetic resonance angiography (MRA) for the diagnosis of CVDs has become increasingly popular because it is generally known to be cost effective, affordable, and safe. MRA is a non-invasive MRI technique, in which known magnetic pulses are used to provide three-dimensional (" 3D ") imaging of arteries and blood vessels that supply blood to the heart and other important organs. Contrast agents can be administered during MRA to improve the visualization of the vascular system. A contrast agent is a substance that, when administered to an individual, can increase contrast contrast (eg, provide enhanced contrast) between a selected target 'tissue' or organ and other areas of the contrast (eg, the rest of the body area). "Vascular" contrast agents can improve the visualization of the vascular system by changing the contrast of the vascular system compared to surrounding tissues. It is usually made by highlighting (over-strengthening) the vascular system (such as blood). Injecting a vascular contrast agent into a patient's blood stream can provide enhanced angiographic contrast 'and allow the attending physician to visualize and detect the diameter of the blood vessels, including those that are extremely small. Correctly clarifying the size and diameter of blood vessels is very important for Cvd diagnosis, because the diameter of blood vessels can show the existence of stenosis, which is characterized by narrowing of blood vessels' and aneurysms, which are characterized by widening of blood vessels. The use of vascular contrast agents in Mri examination can also indirectly detect other types of CVDs ^ For example, 'thrombosis and atherosclerotic injury can replace blood and can be detected indirectly, resulting in blood vessels in contrast-enhanced angiography. Estimation of blocked or narrowed conditions Regardless of the use of vascular contrast agents, the diagnosis of CVDs in the vascular system is still very difficult. For example, physicians must look for dark areas (such as negative contrast areas) in bright (eg, strengthened) blood vessels. ^ Furthermore, with vascular contrast agents, physicians often cannot distinguish between blood vessels that contain blood clots in blood vessels and certain other blockages.

Description of the invention (10). The first and second MRI data sets are then compared to determine the presence of fixed targets within the vascular system. The limitation is that the second MRI group has shown the presence of fixed targets. For example, the first and second MRI data sets can be mixed to generate a third MRI data set, which includes fixed targets and angiography of the vascular system. The third data set may indicate where the fixed marker is located, if present, within the vascular system. If desired, a third MRI data set can be presented on the device to show where the target is fixed in the vascular system. The third MRI data set can also show the size of the fixed standard in the vascular system. The first and second MRI data sets can be mixed, ie the first and second mri data sets are spatially noted in terms of each other. The mixing step may further include interpolating the space of the first or second MRI data sets, so that the first and second MRI data sets have considerable spatial resolution. For example, we can decide which of the first and second data sets has a higher spatial resolution, and interpolate the equivalent spatial resolution of other data sets to a higher spatial resolution. In addition, we can combine the direct estimation combination of the modified image generated by combining the data set with the individual numerical values so noted, and the data elements from the first and second data sets are interpolated. The direct estimation of the intensity of this modified image may include the proportions of the individual values of the interpolated data elements that are noted from the first and second data sets are changed with varying proportions. In addition to its specific affinity for fixed targets, target MRI contrast agents also exhibit specific affinity for non-fixed biological components present in mammalian blood vessels. Non-fixed biological components present in mammalian vascular systems may be, for example, proteins present in vascular fluid pools, such as human serum albumin, _ 14-1221406

Administration to mammals The dose of the target MRI contrast agent is smaller than the general dose of the MRI contrast agent used to develop the vascular system. In order to fully enhance the angiography, the dose of the target MRI contrast agent should be sufficient to cause a blood τ 丨 value That is, the amount of water proton relaxation time in blood is less than 500 milliseconds. In addition, the standard MRI contrast agent should be administered in a dose sufficient to cause a blood T Ti value of less than 300 milliseconds after administration, or cause blood after administration. The amount of Tl is less than 175 milliseconds. Typically, the standard ifcMRI contrast agent is administered in an amount of from about 0.001 to about 5,000 micromoles / kg. In other specific examples, the dose is 0.001 to about 500 micromoles / kg, or from about 0.001 to about 5 micromoles / kg.

Description of the invention (32) Different time after the target MRI contrast agent was administered, the first group of MRI angiography data sets of the vascular system was obtained. Next, a second set of MRI contrast data sets for the fixed target was obtained. Second MRI data is obtained at a point in time when it is appropriate to provide a fixed target to enhance the observable level compared to background blood and tissue enhancement. The time points for obtaining the first and second sets of data depend on the concentration of the target contrast agent in the blood, the rate at which the target contrast agent penetrates into the fixed target, and the specific affinity of the target comparator for the fixed target. If this parameter is not provided with a specific contrast agent, it can be determined by preliminary administration of the agent and better steps of imaging over time. In some specific examples, the optimal time to contrast the target is when the signal strength of the target is near its peak, or when there is a maximum contrast enhancement effect compared to the background blood and tissue enhancement effect. Depending on the patient's body area to be visualized, the desire of the vascular system, and the composition of the fixed target, different MRI imaging acquisition parameters can be applied. These parameters include magnetic resonance (MR), wave order specific in terms of relaxation time, repeat time (TR), echo time (TE), permutation angle, desired image resolution, dimension and field of view. Wave order is an RF pulse that is used in the atom to be developed to disturb the nuclear position. Once the wave sequence has passed through the patient, the core will fall back to the external magnetic field, and this is always the case, so that the radio-frequency energy can be emitted in a signal manner, which can then be measured by the receiving coil, and finally the desired MRA image can be produced. The relaxation time is the time required for the core to return to the normal position. Various relaxation time modes can be applied, each of which will produce different magnetization characteristics and conditions. Typical relaxation times include: Ti, T2, and T2 *. Finally, the repeat time (TR) is the time interval between the application of each RF pulse, and the echo time (TE) is the excitation pulse and the retransmission wave. -36- This paper size applies the Chinese National Standard (CNS) Α4 specification (210X297 mm) )

The wave sequence parameters should be carefully selected to specifically show the pulse sequences that can make Xie Jie A and the blood and blood vessels show bright spots (whitening). For contrast agents that shorten the blood T1 (such as whitening the blood), these sequences include 1-based spoiled gradient echoes, or fast gradient echoes, but are not limited thereto. In a planned specific example, a second MRI data set can be obtained by using a spoiled gradient echo sequence, and the choice of the TR, TE & transpose angle depends on the wave order. For example, Prince PM 5,417,213) Special parameters for brightening blood angiography. For contrast agents that darken the blood due to magnetic susceptibility effects, such as certain iron particles-based agents, a suitable T2 * -based contrast strategy should be used. The artisan should understand that a variety of wave order variations can be used. In a specific example, the target MRI contrast agent is administered in a dose sufficient to cause a fixed target with a T! Value of less than 500 milliseconds. In addition, the MRI contrast agent is administered in a dose sufficient to cause a T! Value of the fixed target of less than 300 milliseconds, or less than 100 milliseconds. Usually, the vascular system and the fixed target data set are obtained from each other in a very short time. For example, two sets of data are taken in a single MRI segment, where individual mammals remain in the same position on the MRI scanner. In a specific example, a single MRI session can last less than 6 hours. In addition, a single MRI session can last less than 4 hours, or less than 2 hours, or less than 1 hour. The first and second MRI data sets are compared to determine the presence of fixed targets in the vascular system. The limitation is that the second set of MRI data has shown the existence of fixed targets. In a specific example, the first and second MRI data sets are represented on an imaging device (such as side-by-side, or sequentially in either order), and the local paper size is specifically adapted to the Chinese National Standard (CNS) A4 specification 210 X 297 mm)

Description of the invention (34) Comparison. In addition, the first and first MRI data sets can be mixed to generate a third MRI data set, which includes fixed targets and angiography of the vascular system. The first and second MRI data sets can be spatially annotated and combined with each other. The combining step further includes spatially interpolating the first or second] y [RI data sets, so that the first and younger data sets are the same spatial resolution. For example, we can decide which of the first and second data sets has a higher spatial resolution, and interpolate another comparable data set with a spatial resolution that is more southerly. In addition, we can combine data sets, which will be indicated by the first and second data sets, and the modified contrast intensity under the combination of individual values of the data elements will be directly calculated. Based on this, the direct calculation of the modified contrast intensity includes increasing the individual values of the annotated and interpolated data elements from the first and second data sets with changes. The third data set may show the location of the fixed target, if any, within the vascular system. If desired, a third MRI data set can be presented on the imaging device to show where the target is fixed in the vascular system. The third data set can also show the size and number of fixed targets in the vascular system. The software method can be used to mix the fixed target with the angiography into a third MRI data set, which contains the fixed target and the vascular system in a single angiogram. In a specific example, the software method performs the following steps: (丨) the first and second data sets are marked with each other, so the two data sets will not be clearly marked; (2) if the data sets have different spatial resolutions, the low resolution The data set is interpolated to the spatial analysis of the higher resolution data set; (3) A third data set is generated, which is a combination of individual numerical values from the first and second data sets marked and interpolated components Modify the direct estimation of the intensity of the radiography; and (4) present the third data __- 38 -____ This paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm) 1221406 A7 B7 V. Description of the invention (35 ) Group to generate a single radiography of fixed target, and learn the size and shape of the angiography and location. The combined angiography is thus helpful for the visualization of the standard and can be used for diagnosis and further therapeutic intervention. Annotating steps are performed to align the anatomical structures within the contrast volume, which may or may not occupy the same area in the respective contrast volumes. When the imaging is absolutely noted (ie, the patient is not moving and the MRI scan is performed in the same imaging section), the amount of data may not necessarily be manipulated for proper anatomy. However, when the patient moves or the angiographic volume is obtained in different angiographic sections, it is noted that it is a necessary step. The special method for indicating the two data sets depends on the method of generating the second data set. The special algorithms for doing this are clearly shown in the literature and are well known to the artisan. When taking MR sequentially, a simple transformation using the data contained in a standard DICOM readhead should be sufficient. In other examples, it may be necessary to use commercial software packages to indicate this to provide the correctness of the desire. Similarly, when it is necessary to interpolate a lower resolution data set to a spatial resolution of a higher resolution data set, any generally acceptable interpolation algorithm may be applied. Once the two sets of data are interpolated to the same spatial resolution, they can be combined to produce a third type of data set, which is a direct estimate of the modified contrast intensity of the individual numerical combinations of the first and second data sets, annotated and interpolated components. These two data sets can be combined using algorithms, as described in the U.S. patent case " Magneto-Vibratory Angiography Data ", Stefancik et al., Serial number 09 / 778,585, published on February 7, 2001 The full text is used as a reference for this case, or other algorithms that can be used to mark and overlap the two angiography generated by the MRI machine.

Description of the invention (36) The data sets are meaningfully combined to produce medically valuable radiography. In addition to simply presenting side-by-side radiography, it can be spatially annotated (to compensate for movement) using minimal variation techniques (eg, Woods, RP ·, SR · Cherry, and JC Mazziotta, Rapid Automated Algorithm for Aligning and Reslicing PET Images , Journal of Computer Assisted Tomography, 1992, 16 (4): 620-633), or according to the nature of the baseline common to the vascular system and target phase. In addition, the data sets can be combined to produce a single merged angiogram including vascular and fixed target data. This combination is performed by using gray-scale angiography, which adds the two contrasts with different specific gravity. For example, the brightness of the fixed target is about twice that of the angiography after classification. One example of this aggravating change is the following formula ... Contrast (x, y) = a (marked contrast (x, y) + b (angiography (x, y)) where a and b are based on the histogram Automatic selection, or automatic selection using target selection from basic angiography. In addition, the combination of data sets can use chromatograms to properly color-code the fixed target angiographic group data superimposed on the angiography by color. The three data sets show the location of fixed targets in the vascular system (such as in arteries or veins), and the location of anatomical targets, such as branch points of blood vessels. The third data set can also identify fixed targets. Number, size, and shape. The third data set can also show the precise position, size, and shape of fixed targets within the vascular arteries. The standard practice with MRI data is to summarize the data set by its natural collection type, that is, individual Collect part of the planar radiography, or use a specific algorithm to project the full amount of data into a representative binary radiography group.

Description of the invention () There are two main algorithms commonly used for MRI in a figurative method, maximum intensity projection (MIP) and volume rendering VR. These algorithms each estimate the contrast presented by the data volume, using methods detailed in academic literature. These figurative methods are often used in most radiographic overview work. For series-based imaging, as is often available in MRI, the rendered imaging can be calculated by these algorithms using each pixel level. Therefore, the imaging generated mainly depends on the intensity difference within the amount of MRI data. The combined data volume (third data set) is generated so that the intensity difference between related structures can be distinguished by these algorithms, which can not only image but also prove the structure in question. In addition to specific affinity for fixed targets, target MRI contrast agents can also exhibit specific affinity for non-fixed biological components present in mammalian vascular systems. Non-fixed biological components in mammalian vascular systems can be proteins such as human serum albumin, fibrinogen, α-acid glycoprotein, globulin, and lipoproteins, such as those present in blood vessel blood pools. Referring to Fig. 1, there is shown a process for improving the visualization of a fixed target in a vascular system using the system and method of the present invention. In step 20, the target's MRI contrast is administered to a patient suspected of having CVD due to the fixed target. The patient receives a target within the MRI scanner, such as any MRI scanner developed by General Electric, Inc., Siemens, Philips, Marconi, and others.

Description of the invention (38) According to the data, it is used to produce angiography. In step 22, a second data set is obtained to obtain a radiograph of the fixed target itself, if it exists. A second data set can be taken when the comparison of fixed standards is enhanced at an observable level compared with blood and tissue background. In step 2 3 ′, the first and second data sets are indicated in each case, and two of the data sets are not explicitly indicated. The special method indicated in the second data set depends on the method used to generate the second data set. The special algorithms for doing this are clearly known in the literature and are well known to the artisan. In the sequential M R acquisition, a simple transformation using the information contained in a standard DICOM readhead should be sufficient. In other examples, in order to provide the correctness of the desire, it may be necessary to use commercial packaged software to indicate it. In step 24, if the data sets have different spatial resolutions, the lower resolution data sets can be interpolated to the spatial resolution of the higher resolution data sets. Any acceptable algorithm for interpolation can be applied. In step 25, the first and second data sets are combined to generate a second data set, which is a direct calculation of the modified contrast intensity of the first and second data sets. The two sets of data are combined using algorithms, as described in the U.S. patent case, entitled "Magneto-Vibratory Angiography Data", Stefancik et al., Serial No. 09 / 778,585, published in February 2001 On the 7th, the full text has been included as a reference for this case, or any other algorithm that can be used to mark and overlap the two angiography produced by the MRI machine. Finally, at step 26, a third data set is generated and imaged to show where the vascular system fixation marker is located.

Description of the invention (39) Two contrast agents (such as vascular MRI contrast agents). This specific example is necessary to obtain acceptable angiography when the specific dose of the target MRI contrast agent is itself too low to induce a sufficient change in the T value of the blood. Use of target MRI contrast agent and vascular MRI contrast agent Another subject of the present invention is to propose a method for determining the presence or absence of a fixed target in a mammalian blood vessel system, in which a target MRI contrast agent and a vascular MRI contrast agent are administered to a breastfeeding Animals, and vascular MRI and target MRI data sets were collected. For example, when the specific dose of the target MRI contrast agent is too low to induce sufficient changes in the T! Value of the blood to obtain acceptable angiography (see discussion above), the additional contrast agent may be It can be administered before, in addition to, or after injection. The order in which the two agents are administered can vary and depends on the contrast agent chosen. Variables include the blood clearance of vascular substrates, which is the ratio of fixed targets bound by the target contrast agent. If the clearance of the vascular contrast agent from the blood is relatively slow and the target can be concentrated quickly, the vascular contrast agent should be administered a second time. If the vascular contrast agent is rapidly cleared from the blood and the target agent is concentrated in a relatively short time, the two agents can be administered simultaneously. In addition, if the target substance takes a long time to concentrate, the vascular contrast agent is administered after the target contrast agent is injected. In some specific examples, it is better to obtain a data set equivalent to the target data before the blood vessel data is obtained, because the contrast-enhanced blood vessels return to the normal angiography (" bright ") level. It takes a long time to lose its contrast enhancement. This is due to the presence of target contrast agents.

Description of the Invention (4〇) — Degree 'standard dry contrast agent penetrates to the target The internal rate and target affinity of the target contrast agent ^ The time to obtain the data set is usually when the signal strength of the fixed target is close to its peak, or when compared with the background blood and tissue, it is at an observable level.

Hour 'can use a fixed index for short T i values. For example, WQ 01/08712 reveals using TR = 36, TE = 5 and 30. The perturbation phase gradient echo sequence of the replacement angle is used to contrast the thrombus in the rabbit jugular vein. If the target is based on iron particles or certain formulations that can cause D2 or T2 * shortening, then the appropriate wave order chosen is to make the target overstrengthened or low-strengthened. For example, Schmitz et al. Used a 3D small-angle fast-excitation gradient echo sequence (TR = 41, TE = 11, and replacement angle called 5.) to image atherosclerotic plaques containing USPIOs. The amount of target contrast agent administered to mammals (such as patients) depends on the agent itself and its specific affinity for the fixed target, the patient's health history, age 'weight, gender, genetics, and physical condition and other factors. Determine the possible level, location and number of fixed targets to be visualized. If the target comparator exhibits a very high specific affinity for its target, it can be administered at a relatively low dose. The final dose is determined by the attending physician after the experiment of varying the dose, and then by the angiography as described above. Suggested doses of affinity and representative agents for fibrin clots are described in WO 01/08712,

Although thorium-based agents are often included, iron oxide particle contrast agents can also be used to strengthen (via negative contrast) the vascular system. This substrate includes ultra-small particles of iron oxide (USPIOs), or single crystal iron oxide particles (MIONs). These agents are absorbed by the iron oxide particles of the endoplasmic reticulum system (RES) and the mononuclear phagocytic cell line (MPS), causing damage to the liver, spleen, lung and active areas of macrophages, such as atherosclerosis, In the distribution.

It should be noted that blood pooling is mobile tissue with a large total volume, such as about 3 liters of plasma volume or in adults. Blood pooling is also filtered by other organs, such as liver, kidney, spleen, and lung, which can affect its volume and distribution, and the size of blood vessels that can be imaged in these organs. Although extracellular and blood pooling contrast agents can be distributed throughout the vascular space, none of them can directly image fixed targets in mammalian vascular systems, and usually do not show a specific affinity for fixed targets. -53- The scale applies to the Chinese National Standard (CNS) A4 specification (210X297 mm) 1221406 A7 B7 V.

Examples of non-fixed biological components present in mammalian blood vessels include blood and blood serum endogenous proteins such as human serum albumin, fibrinogen, acidic choline, globulin, and lipids protein. The dose of vascular MRI effector can be affected by the injection method and the clearance and removal rate of the effector from the blood pool. For example, rapid bolus injection (which distributes the entire blood pool after a single injection) or rapid injection in a short period of time usually results in a bi-exponential decrease in blood concentration of the vascular contrast agent. Because the change in Ti or T 2 is a function of the concentration of the contrast agent, a large change in τ 1 or T 2 should be correct. -56- This paper size applies the Chinese National Standard (CNS) A4 specification (210X 297 mm) 1221406 A7 B7

As a result, when blood concentrations are high and clearance is minimal, the appropriate time for angiographic blood pooling (and therefore the vascular system) is performed immediately after administration of a vascular MRI agent. For example, in “dynamic” contrast MRA, the contrast is designed to be contrasted with blood saset, such as MS-325, immediately after the rapid injection. Generally speaking, the target MRI contrast agent dose Is from about 0.001 to about 500 micromoles / kg, and the vascular contrast agent is administered at a dose of from about 10 to about 300 micromoles / kg. In other specific examples, the standard μ ri contrast The dose of the agent is about 0.001 to about 50 micromoles / kg, and the dose of the vascular MRI contrast agent is about 5 to about 30 micromoles / kg. In addition, the target MRI contrast agent is administered The dose is from about 0.001 to about 5 micromoles / kg, and the vascular contrast agent is administered from about 0.001 to about 3 micromoles / kg. In the method, it is taken to contain Angiographic angiographic MRI data set and target MRI data set. When the target data set is obtained at an observable level suitable for providing fixed target contrast enhancement, this is compared to background blood and tissue enhancement. In some specific examples, target MRI data is taken using spoiled gradient echo sequences.

In addition, the standard Luo contrast agent and the vascular contrast agent can be administered simultaneously, and the vascular MRI data is The target MRI data set was taken before.

Description of the Invention (54) The standard contrast agent and vascular contrast agent can be administered to each other within 2 hours. In addition, the target contrast agent and the vascular contrast agent may be administered within 30 minutes of each other, or within 15 minutes of each other. The vascular mri contrast agent can be administered by rapid infusion or infusion. If the infusion method is used, an infusion time of less than 5 minutes can be used. In other specific examples, an infusion time of less than 10 minutes or less than 3 minutes can be used. The vascular and target MRI data sets can be compared with each other to determine the presence of fixed markers in the vascular system. The limitation is that the target MRI data set can show the presence of fixed markers. The vascular and target MRI data sets can also be combined. For example, the vascular and target MRI data sets can be combined to produce a third MRI data set, which includes fixed standard stem and vascular system radiography. The third data set can also show the location and size (and within the vascular system) of the fixed target (if present). If desired, the third Mpj data set can also be represented on the imaging device to show the location and size of the anchorage (if any) within the vascular system. The data sets can be spatially marked with target and vascular MRI data sets. The combining step also includes spatially interpolating either the blood vessel or the target MRI data set, so that the two have comparable spatial resolution. For example, in a specific example, we can determine which of the vascular or target MRI data sets has a higher spatial resolution; then interpolate the spatial resolution of a comparable other data set to a higher spatial resolution. In addition, the combination step includes a direct estimation of the intensity of the modified angiography, which is indicated freely, the combination of the individual values from the data elements of the intervening blood vessel and the target MRI data set ^ In a specific example, the modified angiography The direct calculation of the intensity includes aggravating the changes in the individual values of the interpolated data elements as noted from the vascular and target MRI data sets. -58- This paper size applies to China National Standard (CNS) A4 (210X 297mm)

After the visualization, there are two main methods commonly used in MRI, maximum intensity projection (MIP) and volume reconstruction (v〇iume ren (jering vr). These algorithms each estimate the amount of contrast presented by the evidence, using the academic method The methods detailed in the literature. These figurative methods are often used in most imaging overview work. For series-based imaging, as is often available in MRI, the imaging presented can be performed by these algorithms using various pixel levels. It is calculated that the intensity difference between related structures can be distinguished by these algorithms due to the amount of generated data (third data set), not only imaging but also proving its structure. In particular, an example of the imaging mode is the standard gray-scale MIP Among them, the fixed target has the highest overall intensity, the vascular system has a moderate overall intensity, and the surrounding tissues have a lower overall intensity. This approach can be extended by adding color coding to specific intensity bands, so that the structure can rely on color and The intensity is distinguished, or its color is limited, compared to the intensity difference in the gray-scale MIP. Another imaging method is the VR statement of the data, which has Highest-intensity fixed targets, vascular systems with moderate overall strength, and peripheral tissues with lower overall strength. Arrangements on VR statements include targeting specific figurative effects and / or specific intensity bands with alpha frequencies. (Opacity) control, color coding of some or all intensity areas. Control color and / or α are general VR indicators and are well known to artisans.

With time, the blood signal gradually declines and the intensity of the thrombus signal continues. In this way, the thrombus becomes brighter than the blood. Early blood vessel data, combined with later data, showed that the thrombus was strengthened. The data indicated on the back are combined again and visualized using the Algotec Provision workstation to show the location of the enhanced blood clots in the vascular system, as described above. Example 3: Analyzing signal strength in a vascular system and using a target substance alone on a fixed target Figure 2A demonstrates that when a target contrast agent is used to develop a vascular system and a fixed target, 'on a fixed target relative to time And signal strength (as a function of concentration) in the vascular system. The figure shows that no significant concentration of contrast agent appeared on the fixed target blood test immediately after the target contrast agent was injected. After a period of time, the target contrast agent concentration on the fixed target increased. This time course depends on the rate of penetration of the target into the fixed target and the specific affinity of the target for the fixed target. After that, the concentration of the target substance on the fixed handle will decrease. Therefore, the signal strength on the fixed target increases, reaches the highest point, and then decreases. The best time to capture a fixed target image is when the signal intensity in the fixed target is close to its peak, and the target in other surrounding tissues minimizes the effect of the target. It is understood that the target contrast agent exists in the blood (vascular system, such as veins) and when the target is fixed. If image data is acquired immediately after injection, the signal strength of the blood will be comparable or greater than the signal strength of the fixed target. The figure demonstrates that when the target is significantly enhanced by the fixed target, the signal enhancement of the vascular system β. This previous data set can generate an angiogram-the imaging of the vascular system. Because here _____ -62- _ This paper size applies Chinese National Standard (CNS) A · 4 size (210X 297mm) 1221406 A7 B7 V. Description of the invention (59) The fixed standard in imaging can be brighter. It is blocked around the blood, so this imaging alone is not the best imaging for detecting fixed targets. If the second set of imaging data is acquired when the signal in the blood approaches the baseline level, but the signal intensity of the fixed target is still high at this time, as shown in the figure, the contrast of the fixed target to the vascular system is very high. The second development data set can form a fixed target. Comparing these two data sets will further determine the correlation between the standard and the vascular system. : After using the vascular agent followed by the target agent, analyze the signal strength on the vascular system and fixed target. Figure 2B proves that when the target contrast agent is administered to the patient after the vascular agent is administered, Fixed targets and signal strength (as a function of concentration) can be displayed in the vascular system. The figure shows that there is no significant strength in fixing the target (thrombus) immediately after the injection of the standard contrast agent. This is because the target contrast agent exists on the fixed target. After a period of time, the target contrast agent is on the fixed target. Concentration will increase. This time depends on the rate of penetration of the target to the fixed standard and the specific affinity of the target agent for the fixed standard. After this time point, the concentration of the target substance on the fixed standard stem will decrease. Therefore, the signal strength of the fixed indicator rises to a maximum value, and then decreases. The best time to develop a fixed marker is when the signal intensity in the fixed marker is close to its peak, and when the intensity of the target substance in other garden tissues is the lowest. On the whole, the 'standard dry contrast agent exists in both vascular systems (such as veins) and fixed handles. -However, due to the administration of low-dose target contrast agents, the signal strength of the blood may be too low to produce clear imaging of the blood vessels. Extracellular or blood pooled contrast agents can be administered to a patient ' before, simultaneously with, or after the target contrast agent to provide imaging of the vascular system.

Invention ~ 6〇 '~ " " When the second data set is an independent MRI scan result, the output data set is generated according to the following formula: 0: ⑴ 0 = α Α + / 3 Τ (Π ) 〇i = max (a A, / ST) In these formulas, 'α and the variable weighting coefficient are not predetermined. In Equation I, the output data set 0 is generated by general formal arithmetic. In waiting, output group 0 is generated by taking only the highest coordinate values in space, that is, the strongest signal. In Equation I, the values of α and / 3 are preferably in the range of ι > α, y5 >, and α + not = 1 is better. The range of this emphasis coefficient can make the output data set and the contribution data set have approximately the same magnitude of intensity, and is only used to ensure that the output data set does not have any significant performance error. More detailed detection is required to ensure correct output so that the data set can use the most representative range for the stored variant. Typically, in MR imaging, the DICOM data set does not require this dynamic range operation, so for most examples, α, the point coefficient should be sufficient. In Equation 11, the values of α and / 9 are the same as 妤 compared to 妤. In this example, the data set 0 generated in a single image is a contrast-enhanced fixed target (such as a blood test) and a contrast-enhanced blood vessel. Departments (such as blood pools) have a single representative. Alpha and inoperability allow complementary base strength differences between the A and T data sets to ensure optimal operation. Generate appropriate data sets that represent blood vessels (blood pools) and fixed targets (thrombus) to present results. .

In these equations, α is less than the coefficient that is relatively heavier. The preferred value is in the range of 1 > α, no, r > 0, and the better α + / + T = 1. In equation (111), the data set masked by the weighted fixed target (such as a thrombus) is added to the data set containing the data of the vascular system, and when properly performed, the fixed target (such as a thrombus) and the blood vessel can be generated The data sets of the systems can be distinguished from each other, and the surrounding tissues can also be distinguished by the intensity difference. Equations (IV) and (III) are significantly similar, except that the vascular data is added in its entirety to a data set containing a fixed target, such as a thrombus. Equation (V) represents the generation of output data from the two fragment components of the original development area. Proper weighting of each of the three components can produce an output data set with the greatest difference in strength between the three components.

Description of the invention (63) The veins are crushed twice along the 5 mm section. After 4 minutes, the clip was removed and a 5 mm jugular vein slice was separated with a microvascular clip. Thrombus can be generated by injecting 100 μl of a mixture of 3.7 units of thrombin, 0.06 M CaCl2, and rabbit whole blood. After 4 minutes, remove the clip. Allow the thrombus to mature for about 50 minutes. 1.0 ml of a 5 mM structure I I I solution (2 micromolar / kg) was administered via the ear vein. After 30 minutes, the animals were placed in a General Electric Signa LxC Vi 1.5 high-voltage scanner, and the first set of MRI data sets and images were obtained using the 3D RF spoiled gradient echo sequence (SPGR) under the following parameters: TR = 39 ms, Τ = 3.1 milliseconds, permutation angle = 40. , Field of view = 8 cm, acquisition width = 3 1.25 kHz. Apply chemical lipid saturation and saturation bands above and below the 40 mm space.

FIG. 4A illustrates the maximum intensity projection (MIP) of the first image. There is a brighter area on the left hand side of the MIP. FIG. 4B shows the MIP of the second image obtained immediately after the injection of the vascular agent Gd-DTPA-BSA. In this MIP, blood vessels such as the carotid artery and the iliac vein can be easily seen. Fig. 5 is an image generated by combining the data groups represented by Figs. 4A and 4B. Since the two images have the same resolution, and the two scans have the same anatomical position, the combined shadow lane seedlings should be equal to the equation U) ·· 〇 = 4 · 2Α + 0 · 8Τ. In the combined image of FIG. 5, it is obvious that the highlight area enhanced by the blood test target is equivalent to the right carotid artery of the animal, and it can be inferred that there is a thrombus in the right carotid artery of the animal.

The imaging sequence was repeated within the next 80 minutes. A selected area of the axis was analyzed for thrombus and normal jugular vein (RC) I). Before the injection, the thrombus and blood had the same intensity in the MR image. The first image taken after the target contrast injection showed a 4.4-fold increase in blood compared to the pre-injection image. The thrombus was also enhanced compared to the pre-injection image. The second scan after the injection proved that the thrombus was strengthened 2 · 2 times compared to the blood. The thrombus remained brighter (about 3 times brighter) than the blood during the study. In summary, the first image (vascular MRI image) after the target contrast agent injection showed that the blood vessels were brighter. Over time, the images (fixed MRI images) proved that the blood signal was reduced, and fixed targets (such as blood clots) seemed brighter because they had stronger signals compared to blood. Rabbit: After injecting the target MRI contrast agent, acquire a fixed target MR image, then administer the vascular MRI contrast agent and capture the blood vessel μR image. 3.1 kg of female New Zealand white rabbits were treated with ketamine (50%) G / kg), anesthesia (2.5 g / kg) and Roppong (5 mg / kg) anesthetized with a blend, and then maintained with sodium pentobarbital (about 35 mg / kg, as needed) . An intravenous catheter (24 g) was placed in the ear vein and ear artery. Separate jugular vein and carotid artery. Take a 18-gauge needle and place it on a blood vessel with 3-0 suture suture, which can be -70 at the carotid artery. This paper size applies the Chinese National Standard (CNS) Α4 specification (210 X 297 mm) ---- ---- 1221406 A7 B7 5. Description of the invention (π) causes narrowing. After that, the needle was taken out, and a 5-meter arterial segment was cut out at the distal end of the stenosis with a microvascular clip. The artery was crushed twice more along the 5mm section. Loosen the proximal vascular clamp to allow blood to flow into the segment for about 3 seconds. The clamp is clamped again, and the artery is crushed twice along the 5 mm segment. After 4 minutes, the clip was removed and a 5 mm jugular vein slice was separated with a microvascular clip. Inject 100 microliters of 37 units of thrombin, a mixture of 006 M CaCl2 and rabbit whole blood to form a thrombus. Remove the clip after 4 minutes. 々 The thrombus was heated for 4 5 minutes. Animals were placed in a Generai Electric Signa LxCVi 1.5 high-voltage scanner and developed using 3E) RF spoiled gradient echo sequence (SPGR) under the following parameters: TR = 39 ms, τ e = 3.1 ms, displacement angle = 40 Degree 'field of view = 8 cm, wave width of image capture = 31 25 kHz. Applications Chemical lipid saturation and saturation bands above and below 40 mm space. After a scan prior to the injection of the standard MRI contrast agent, 1.5 ml of a 4.2 mM structure I solution (see above) (2 μmol / kg) was administered via the ear vein to repeat the developmental wave sequence at the next go minute. After 80 minutes, blood was injected to pool the vascular MRI contrast agent Gd-DTPA-BSA, 3 ml of 80 mM Gd solution (80 micromolar Gd / kg). Capture additional developments in the same wave sequence. On selected axis films, a focal area (rOI) analysis was performed for thrombus and normal jugular vein. Before the target contrast agent is injected, the thrombus and blood are of equal strength. The first image acquired after the injection shows that the thrombus has a significant enhancement (such as a bright spot), while the blood is slightly stronger, which decreases rapidly. Compared with blood, the thrombus is 2-3 times brighter. After the blood pooling agent is injected, the signal strength of blood and thrombus increases sharply, providing a detailed view of the blood vessel system. Comparing and combining the two images provides a detailed analysis of the fixed target (thrombosis) and its location.
